PRECAUTIONS

1.0 Precautions

The following precautions should be taken when working with LMI metering pumps.

Please read this section carefully prior to installation.

Protective Clothing

ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or

near your metering pump. Additional precautions should be taken depending on the solution

being pumped. Refer to Safety Data Sheets (SDS) precautions from your solution supplier.

Water Pre-Prime

All LMI pumps are pre-primed with water when shipped from the factory. If your solution is not

compatible with water, disassemble the Pump Head Assembly. Thoroughly dry the pump head,

valves, O-rings, balls and diaphragm. Reassemble head assembly tightening screws in a

crisscross pattern. Refill the pump head with the solution to be pumped before priming the

pump. (This will aid in priming.)

Liquid Compatibility

CAUTION: The evaluation performed by ETL was tested with water only. The pumps are

certified to NSF 61 with: sodium hypochlorite (12.5%), sulfuric acid (98.5%), sodium hydroxide

(50%), and hydrochloric acid (30%). Determine if the materials of construction included in the

liquid handling portion of your pump are adequate for the solution (chemical) to be pumped.

Always refer to the solution supplier and the Milton Roy Chemical Resistance Chart for

compatibility of your specific Milton Roy metering pump. Contact your local Milton Roy distributor

for further information.

Tubing Connections

Inlet and outlet tubing or pipe sizes must not be reduced. Outlet tubing size must not be

increased. Make certain that all tubing is SECURELY ATTACHED to fittings prior to start-up (see

section 3.3 Tubing Connections). ALWAYS use LMI supplied tubing with your pump, as the

tubing is specifically designed for use with the pump fittings. It is recommended that all tubing be

shielded and secure to prevent possible injury in case of rupture or accidental damage. If tubing

is exposed to sunlight, black UV resistant tubing should be installed. Check tubing frequently for

cracks and replace as necessary.

Fittings and Machine Threads

All fittings should be hand-tightened. An additional 1/8 - 1/4 turn after the fitting is snug may be

necessary to provide a leak-proof seal. Excessive overtightening or use of a pipe wrench can

cause damage to the fittings, seals, or pump head.

Most LMI pumps have straight screw machine threads on the head and fittings and are sealed

by the O-rings. DO NOT use Teflon® tape or pipe dope to seal these threads. Teflon® Tape

may only be used on NPT threads.

Plumbing

Always adhere to your local plumbing codes and requirements. Be sure installation does not

constitute a cross connection. Check local plumbing codes for guidelines. LMI is not responsible

for improper installations.

PRECAUTIONS

Back Pressure/Anti-Syphon Valve

If you are pumping downhill or into low or no system pressure, a back pressure /anti-syphon

device should be installed to prevent over pumping or syphoning. Contact your LMI distributor

for further information.

Electrical Connections

WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a

properly grounded grounding-type receptacle with ratings conforming to the data on the pump

control panel. The pump must be connected to a good ground. Do not use adapters! All wiring

must conform to local electrical codes. If the supply cord is damaged, it must be replaced by the

manufacturer, stocking distributor, or authorized repair center in order to avoid a hazard.

Fuse (all models) and Battery

CAUTION: Battery may explode if mistreated. Do not recharge, disassemble or dispose of in fire.

The battery and fuse are internal, factory serviceable parts, and must be replaced by the factory

or a qualified distributor with parts of the same type and rating.

Flooding

WARNING: Install this pump in a location where flooding cannot occur.

Ground Fault Circuit Interrupter

WARNING: To reduce the risk of electric shock, install only on a circuit protected by a Ground

Fault Circuit Interrupter (GFCI).

Line Depressurization

To reduce the risk of chemical splash during disassembly or maintenance, all installations

should be equipped with line depressurization capability.

Over Pressure Protection

To ensure safe operation of the pump it is recommended that some type of safety / pressure-

relief valve be installed to protect the piping and other system components from failing due to

excessive pressure.

Chemical Concentration

There is a potential for elevated chemical concentration during periods of no flow, for example,

during backwash in the system. Steps, such as turning the pump off, should be taken during

operation or installation to prevent this.

See your distributor about other external control options to help mitigate this risk.

Retightening Components

Plastic materials will typically exhibit creep characteristics when under pressure over a period of

time and to insure a proper fit it may be necessary to retighten the head bolts periodically. To

insure proper operation, we recommend tightening the bolts to 25 inch-pounds after the first

week of operation and on a monthly basis thereafter.

PRECAUTIONS

Flow Display

The accuracy of the flow value as shown on the pump display is highly dependent on the

specific application. Calibration is necessary in order to display an accurate measure of the flow.

Spills

CAUTION: Spills of Dangerous chemicals should be cleaned up immediately.

4.0 Enhanced Control Operation

This manual covers features supported in the enhanced control model Excel

XR Series

pumps. Enhanced control features are driven by a variety of external inputs and outputs.

Please see section 5.0 Cable Wiring for information on connections, signal types, and

requirements.

4.1 Analog Mode

Analog mode allows control of the pump using an external 0 - 20 mA signal. The analog

mode home screen is shown in Figure 1.

(866) 433-6682 • (281) 359-8538 • [email protected] • www.novatech-usa.com

OPERATION

Press Left or Right to navigate to the parameter entry boxes. Enter the desired

flow rates and currents at points P1 and P2. The range of allowable values for flow rate

are from zero to the maximum capacity of the pump. Input signal current can range from

0.0 to 20.0 mA. Press Save to retain the entered values and Exit to return to the

analog mode home screen. Press Exit without pressing Save to exit without

modifying the parameters.

The linear relationship between signal current and flow can be increasing or decreasing.

If the input signal is outside the operating range defined by the values entered by the

user, the pump output will plateau at the defined flow limits. If the current exceeds 22 mA

the Signal Over Range icon will appear in the notification bar.

Any input current value of 0.5 mA or less will cause the pump to stop pumping and the

Loss of Signal icon will appear in the notification bar. The pump status indicator will

remain green, showing the pump is still in “run” mode. When the input current rises

above 0.5 mA again, the pump will resume pumping and the Loss of Signal icon

will be cleared from the notification bar.

Press the Start / Stop button to make the pump dose at the calculated flow rate. Starting

and stopping can be done manually by pushing the Start / Stop button or remotely using

the Remote Start / Stop function.

4.2 Pulse Mode

In pulse mode, the pump delivers a programmable volume of fluid, for a programmable

number of incoming pulses from an external device (typically a flow meter). The result is

a flow output that varies as the frequency of the incoming pulses varies, allowing the

pump to track the external input.

From the pulse mode home screen (Figure 3) press the Up or Down buttons to get to

the pulse adjust screen (Figure 4).
